A lovely airy and bright easy Summer dress

Very stylish and perfect for summer

Yes, I recommend this

I have had my eye on this dress for a while but was slightly put off because some reviewers said it was tight under the arm holes. But I sized up and went for a petite ( again on the advice of other reviewers) and it is perfectšŸ™‚

Beautiful in hot weather

Yes, I recommend this

Beautifully flattering and cool in the heat but I had to return it despite being a size 10 as the arm holes are too narrow and restricting. 😄 Tried the 12 bit too much material everywhere. Wouldn’t wear it enough for Ā£50!!

Wonderful summer dress

Yes, I recommend this

Just love this dress, so cool and comfortable. Ordered the petite size as the length is just perfect (5’6ā€) for me. Only worn it twice however on both occasions several people have commented on the colours and style.

Great for hot weather

Lovely dress especially for the hot weather the fabric is quite thin fyi. The tall size 12 fitted perfectly. So great to have tall options.

Summer in a dress - More petite options please!!!

Yes, I recommend this

Absolutely love this, relaxed without being baggy, gorgeous ice cream colours, quintessential summer stripes. The big plus is it being available in Petite so the proportions are perfect. I have had to return a couple of other dresses that I love but the Regular is just too long in the body and of course length. So please M&S, as with this lovely dress give us the option of a Petite….

Great Beach Dress!

Yes, I recommend this

Lovely dress but just wouldn’t get the wear out of it like the others I chose - I agree it was a bit tight under the arms so I sized up and it was perfect. A sad return.

Great summer dress

Yes, I recommend this

Beautiful summer dress, looks lovely with gold necklace and clutch. Can’t wait to wear it. Only slight criticism is that the arm hole could be 1-2cm lower as it’s quite high in the armpit
